[4-[[4-anilino-1-naphthyl][4-(dimethylamino)phenyl]methylene]cyclohexa-2,5-dien-1-ylidene] dimethylammonium chloride (C.I. Basic Blue 26) (FV52673) official sources, CAS, ECHA and PubChem data

Provenance page

Official sources for identity and EU status

Open the identity source for synonyms, structure, canonical SMILES, CAS context, and cross-registry identifiers.

Primary open identity surface for broad molecule inventory expansion.

Useful when the site needs richer annotation text, hazard summaries, or evidence blocks beyond core identifiers.

Official publication surface for substances of very high concern.

Best official starting point for SCIP duties, article-notification rules, and Waste Framework Directive context.

Searchable public database for SCIP article notifications under the Waste Framework Directive.

Best official starting point when a chemical needs a broader ECHA info layer beyond a single framework registry.

Use when a substance moves from watchlist interest to authorisation logic.

Important for legacy brominated flame retardants and high-risk persistence topics.

Useful for upcoming classification pressure even before an outcome page is curated.

Useful for classification and labelling checks, hazard pressure, and CLP context around monitored chemicals.

Secondary open source for cross-checking identifiers and screening context.

Relevant for cosmetics and formulation compliance questions.
